vAPoR-BuRNER.

SPECIFICATION forminglpart'iof Letters Patent No. 239,112, dated. March 22, 1881.

Application filed November 30, 1880.

' of New York, have invented a certain new and useful Improvement in Vapor-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it pertains to make and useit, reference being had to the accompanying drawing, which forms part of this specification.

My invention relates to vapor-stoves, Vaporburners, or hydrocarbon-burners of any and every form of construction; and it consists in a construction hereinafter described and claimed.

The drawing represents a central longitudinal section, taken on a vertical plane, of one form of burner. i

B'desiguates the jet-orifice or vapor-disand D is a feed-pipe leading from the fuel-res- 4 y ervoir to the burners.

The main objection to vapor or hydrocarbon burners, and the use of petroleum or its products by first vaporizing them, is that the vapor and flame issue from the burner in irregular'and sudden jets, and the flame is very apt to beextinguished, and, the fluid continuing to flow over the heated surfaces, soot is formed, and clouds of it fill the apartment where the burner is being used. These defects render the burncrs of no value, and they cannot be trusted to burn, except While being closely' Watched. l find these sudden jets, which more resemble explosions, to be caused by the fuel being vnporized faster than it is consnmed or escapes from the burner, thereby causing a pressure to exist between the burner-orif1ce and the fuel.` The rapor or gas thus forces the fuel some distance back in the feed-pipe, and while the fuel is thus being held back from the vaporizing -chamber no vapor is being formed, and will not be formed until tha-t which is already formed is so far consumed as to allow the fuel to once more come to the heated part of the burner, when an excessive amount of vapor is again instantly formed, and again the fuel is forced back, and thus these pumpin g actions are very rapidly kept up, and very often they are of such force as to extinguish the flame. Several attempts have been made to control the flow of fuel to the burners by filling the supply-pipe with various substances, such as iron clippings or filings, silica, emery,

(NG model.)

or their'equivalents. These may possibly have been of some little benefit if the packing filled the feed-pipe pretty tightly and the lighter petroleum products were used for fuel; but they are not positive in their action, and the heavy products would not flow through these packiugs fast enough. Then, again, these packings soon became clogged up.

I have discovered, by experimenting with a check-valve in the feed or supply pipe, that both the flow of the fuel to the burner and the back-pressure of the vapor on the fuel are thus perfectly controlled. The check-valve feeds the vaporizing-chamber automatically, and the result is a steady fiame and no danger of its being self-extinguished, and the heavy -oils may be used as well as the light ones. Just the instant the least quantity of vapor is made more than is passing through or more than can pass through the burner-orifice it will cause a slight pressure on the check-valve and close it. No more fuel can then go to the burner; but it is just as quickly' opened, so that the flow of fuel through the check-valve depends upon the size of the burner-orifioe and the capacity of the vaporizing-hamber, and after the burner `is once fairly started all other valves are useless. Oonseqnently there can be no fluctuation of the flame.

I do not limit myself to the use of a checkvalve of any particular construction. N either do I limit myself to the placing of a checkvalve in any particular part of the burner or feed-pipe; nor to the use of only one checkvalve in one burner, as I am now using a burner which has two check-valvesin it. One is near the burner-orifice and the other is just back of the vaporizing-chamber. One valve is in a vertical pipe 5 the other valve is in a horizontal pipe. i

I do not wish any back-pressure on the fuel being vaporized, and any equivalent means which Will prevent that result is myiinvention.

I' do not claim either the check-valve or the burner independently of each other.

What I claim is- In combination with a vapor or hydrocarbon burner and its fuel-feed pipe or pipes, one or more check-valves, or their equivalents, substantially as described.

I, CHARLES S. PHILIPS.
